ZF 4642.103.057 OUTPUT for WG150 | OEM Genuine Part

Overview

The ZF 4642.103.057 OUTPUT for WG150 is a critical driveline component engineered to transfer rotational force from the transmission’s planetary gearset to the output flange. Positioned at the rear of the WG150 series housing, this OEM genuine part ensures precise torque delivery and maintains axial alignment under heavy loads. The SKU 4642.103.057 is machined from high-strength alloy steel to withstand continuous stress in industrial and commercial vehicle applications. When paired with a robust TRANSMISSION HOUSING, this output shaft assembly guarantees long service intervals and reliable power transmission.

Symptoms of Failure

• Oil leaks near the rear seal: A worn 4642.103.057 output shaft can damage the sealing surface, causing transmission fluid to drip from the output area—a common long-tail search query for “ZF WG150 output shaft leak.”
• Gear slipping under load: Excessive wear on the splines or bearing journals leads to intermittent power loss, especially during acceleration or hill climbs.
• Vibration or driveline shudder: A bent or fatigued output shaft produces noticeable oscillations at highway speeds, often misdiagnosed as a universal joint issue.
• Metallic debris in transmission fluid: Flaking or pitting on the shaft surface introduces ferrous particles into the oil, accelerating wear on the TRANSMISSION HOUSING and internal bearings.

Technical Specifications

Compatibility

This genuine ZF output shaft is designed primarily for the WG150 series, but it also fits select models in the WG180 and WG200 families where the output flange interface matches. It is commonly used in ZF Ecomat and Ecolife transmissions for buses, fire trucks, and construction equipment. Always verify the spline count and bearing journal dimensions against your existing assembly. For proper installation, ensure the TYPE PLATE matches your transmission model and secure the shaft using a GROOVED STUD to prevent axial play.
